Description

Guiding device for asphalt pavement paving

Technical Field

The invention relates to the technical field of road engineering equipment, in particular to a guide device for paving an asphalt pavement.

Background

The asphalt road theory is a common facility in daily life, compared with a cement concrete road, the asphalt road has the advantages of smooth surface without joints, small driving vibration, low noise, quick construction, short construction period, quick open traffic, simple and convenient maintenance, and the existence of the asphalt road greatly facilitates traffic transportation and has great effect in many aspects;

the asphalt road structure layer mainly comprises a surface layer, a base layer (bottom layer) and a cushion layer, wherein when asphalt is paved, firstly a foundation, namely the cushion layer is paved, then the cushion layer is cleaned, adhesive layer oil is sprayed after the cleaning is finished, then the base layer is paved, when asphalt is paved on scenic spots or municipal roads, before the bottom layer is paved, kerbs are needed to be paved to limit the paving range, meanwhile, the asphalt is prevented from scattering and overflowing in the rolling process, after the bottom layer is paved and rolled, the surface of the base layer is cleaned, when the bottom layer is dried but not hardened, the surface layer is paved, the paving of the surface layer needs to be carried out edge pressing treatment when the surface layer is hot, then follow-up treatment such as crack filling and rolling is carried out, thus the asphalt paving is completed, and the asphalt paving thickness of the asphalt is different due to different purposes or areas of the road, for example, the thickness of the asphalt surface layer of a common highway is not less than 15cm, at present, about 20cm is used, two or three layers can be made on a common road, the thickness of the common road is thinner than that of a high-speed road, two asphalt layers (one layer is 4cm, the other layer is 6 cm) are made on a common municipal road for 10cm, the thickness of soil asphalt for rural reconstruction is 5cm, in a landscape, a roadway generally adopts a modified asphalt pavement, the thickness of the asphalt is 70mm, the bottom layer is 40 thick coarse particles, the particle size is 16mm, the surface layer is 30mm, and the particle size is 10-12mm, if the road needs an overweight truck, the particle size of the surface layer needs to be increased to 13mm, but the asphalt paving machine in the market at present only can pave asphalt with one thickness, and if the asphalt paving thickness needs to be changed, the paving machine needs to be replaced, so that the universality of the traditional paving machine is lower, and the replacement is more troublesome; in addition, it should be noted that, in the asphalt paving process, the advancing direction of the conventional paving machine is controlled by workers in the operating room, and as the asphalt paving environment is very hard (asphalt temperature is high, paving can be performed only when weather is good, and weather such as rain cannot be performed), fatigue inevitably occurs after long-time working by workers, so that the advancing route of the paving machine deviates, or the advancing direction of the paving machine also subjectively changes at a corner, so that the asphalt paving is uneven, namely, the paving machine can not be covered when being close to a curb, and therefore, other working day workers are needed to fill the asphalt, which is troublesome;

the advancing speed of the paving machine is matched with the paving thickness of the paving machine, the advancing speed of the paving machine can be correspondingly changed under the condition of different paving thicknesses, and if an operator controls the moving speed of the paving machine, the speed can be excessively fast when a thick pavement is paved, so that the pavement on the asphalt surface is not uniformly paved;

therefore, in order to avoid the above situation, it is important to design a device capable of regulating and controlling the moving direction of the paving machine from time to time and changing the advancing speed of the paving machine along with the asphalt paving thickness.

Detailed Description

The foregoing and other aspects, features and advantages of the invention will be apparent from the following more particular description of the embodiments of the invention, as illustrated in the accompanying drawings in which reference is made to figures 1 to 18. The structural contents mentioned in the following embodiments are all referred to the attached drawings of the specification.

Exemplary embodiments of the present invention will be described below with reference to the accompanying drawings.

Embodiment 1, this embodiment provides a guiding device for asphalt pavement paving, referring to fig. 1, it includes a vehicle body 1, and two sets of track wheels 37 are arranged under the vehicle body 1 at intervals, the track wheels 37 mainly include tracks, a base frame, driving wheels, guide wheels, support wheels, tension mechanisms, internal suspensions, etc., because the track wheels 37 are prior art, only the shape is shown in the specification drawings of this patent, and we rotate two rotating shafts 2 installed under the vehicle body 1 and respectively connect with the rotating shafts of two driving wheels in the two sets of track wheels 37, make them cooperate and rotate synchronously, and we are equipped with a feeding hopper 10 at the upper end of the head of the vehicle body 1 for dumping asphalt stones, but because the particles of different layers of asphalt stones are different in size, such as the particles of bottom layer are usually medium particles, and the most of surface layer are small particles, in order to prevent larger-particle stones from entering the hopper 10, two mutually meshed crushing rollers 35 are arranged at an inlet of the hopper 10, an inclined plate is arranged at the upper end of the hopper 10, so that asphalt stones are gathered to the meshed parts of the two crushing rollers 35, so that when the two crushing rollers rotate synchronously, the larger-particle stones can be crushed, and in order to enable the two crushing rollers 35 to rotate oppositely, namely one crushing roller rotates clockwise, the other crushing roller rotates anticlockwise, so that the crushing effect is realized, therefore, two mutually meshed third gears 36 are rotatably arranged on the vehicle body 1, the two third gears 36 are respectively connected with rotating shafts of the two crushing rollers 35 through belt transmission, so that the two crushing rollers 35 can be driven to start synchronously as long as one of the third gears 36 is driven, and in the drawings in the specification of the patent, the two crushing rollers 35 are fixed in position, so that the size of crushed particles can only be in a certain range, preferably, the rotating shafts 2 of the two rotating rollers can be rotatably arranged on different sliding blocks, then the sliding blocks are driven to move, so that the meshing gap between the two crushing rollers 35 can be controlled, and then the crushing fineness of the crushing rollers can be controlled, and the positions of the sliding blocks need to be positioned after being changed, and the belt transmission connected between the crushing rollers 35 and the third gear 36 needs to be tensioned;

the asphalt stone material will fall on the conveyor belt 11 arranged in the vehicle body 1 after passing through the feeding hopper 10, and the asphalt stone material will fall after reaching the tail of the conveyor belt 11 as the conveyor belt 11 moves towards the tail of the vehicle body 1, so as to avoid the asphalt stone material from adhering to the surface of the conveyor belt 11 and entering the vehicle body 1 along with the conveyor belt 11, and falling into the vehicle body 1 (the lower part of the conveyor belt 11, etc.), which causes a safety hazard, and avoid cleaning burden for workers, as shown in figure 8, a scraper 24 is arranged below the tail of the conveyor belt 11 in the vehicle body 1, and the sharp part of the scraper 24 abuts against the surface of the conveyor belt 11, so that the asphalt stone material adhering to the surface of the conveyor belt 11 is cleaned, a baffle 23 is arranged above the head of the vehicle body 1, which is positioned on the conveyor belt 11, and the bottom end of the baffle 23 is attached to the surface of the conveyor belt, so as to avoid the asphalt stone material from falling from the gap between the head of the conveyor belt 11 and the vehicle body 1 to the inside of the vehicle body 1 In addition, a bidirectional auger 12 is rotatably arranged at the tail part of the vehicle body 1 below the conveyor belt 11, the bidirectional auger 12 is provided with two groups of screw conveying mechanisms which are symmetrically arranged and rotate in different directions on a shaft, after the asphalt stone falls onto the bidirectional auger 12, one part of the asphalt stone directly falls onto a foundation, and the other part of the asphalt stone is transferred to two sides along with the rotation of the bidirectional auger 12, so that the asphalt stone is more uniform when being stacked on the ground, and the subsequent asphalt laying effect is better;

after the asphalt stone falls to the ground, paving and pressing are needed to form a relatively flat surface, so as to refer to fig. 1 and 8, a fixing frame 13 is arranged at the tail part (right side in fig. 1) of a vehicle body 1, the ground at two sides of the fixing frame 13 is close to the surface of a foundation, so that the asphalt stone does not exceed the limit range of the fixing frame 13 when being uniformly spread, the asphalt stone on the ground is spread after the fixing frame 13 advances along with the vehicle body 1, then subsequent edge pressing treatment and repeated rolling can be carried out, attention is needed to be paid, the asphalt pavement can be used after being cooled, the surface of the foundation is not an absolute plane, namely the surface of the foundation is also provided with uneven or broken stones, therefore, the lower end of the connecting part of the tail part of the vehicle body 1 and the fixing frame 13 can be directly touched with a bulge or directly collided with the stones and the like, so that the lower end surface of the vehicle body is worn, and the vehicle body is a part of the vehicle body 1 and is not easy to repair and replace after being worn, therefore, a part of the part is removed, so that the part has a certain height from the ground, and in order to prevent asphalt stones from bouncing and splashing after falling to the ground, referring to fig. 5, a blocking plate 25 is vertically and slidably installed at the connecting part of the vehicle body 1 and the fixed frame 13, facing to the crawler wheel 37, and a compression spring is connected between the upper end of the blocking plate 25 and the vehicle body 1 and is always in a compression state, and a plurality of rotating wheels 26 are rotatably installed below the blocking plate 25, facing to the crawler wheel 37, and because of the existence of the rotating wheels 26, a certain gap is formed between the lower end of the blocking plate 25 and the ground surface, and the lower end of the blocking plate 25, facing to the crawler wheel 37, so that in the moving process, even if the arresting plate 25 is contacted with the bulge or the small stone, the arresting plate can ascend due to the existence of the rotating wheels 26 and the chamfers to avoid the collision with the straight surface, and the arresting plate 25 is more convenient to detach and easier to replace or repair after being worn;

in addition, in order to avoid that the wheels 26 on the barrier plate 25 are always in contact with the ground and are continuously worn when the device is transported, referring to the attached drawing 1, round holes are arranged at corresponding positions of the barrier plate 25 and the vehicle body 1, and when the device is transported or does not work, the limiting columns are inserted into the round holes between the barrier plate 25 and the vehicle body 1, so that the lower end surface of the barrier plate 25 is improved, and the above effects are achieved, when the device is operated, the limiting columns only need to be pulled out, the barrier plate 25 can fall down without affecting the operation, and it needs to be noted that the limiting columns are stored to avoid loss, the limiting columns can be connected with the vehicle body 1 by chains, but after the limiting columns are pulled out, the limiting columns move along with the vehicle body 1 and can shake to affect the clamping of a transmission part, so that the vehicle body 1 can be provided with grooves with certain elasticity, and then the grooves are placed in the grooves after the limiting columns are pulled out, the limit column is not shaken.

Example 2, in order to make the traveling road of the paving machine always parallel to the central line of the road, referring to fig. 1 and 5, we have a guide rod 7 longitudinally slidably mounted on the side of the blocking plate 25 facing the track wheel 37, and two guide springs 39 are spaced at an end of the guide rod 7 below the blocking plate 25, and the opposite ends of the two guide springs 39 are fixedly mounted on the guide rod 7, and the other ends are movably connected, i.e. not connected with the guide rod 7, and the opposite sides of the two guide springs 39 respectively abut against two longitudinal side walls of the connecting block 27, referring to fig. 6, the connecting block 27 is longitudinally slidably mounted on the side wall of the blocking plate 25 facing the track wheel 37, and when asphalt pavement is started, the end of the guide rod 7 extending out of the vehicle body 1 contacts with the side wall of the curb, and the end face of the guide rod 7 contacting with the curb is a round surface, at this time, the guide spring 39 on the side close to the curb is stretched, and the guide spring 39 on the side far from the curb is compressed, so that the guide rod 7 always tends to move toward the curb, if the vehicle body 1 deviates or turns during the forward movement, the guide rod 7 slides on the blocking plate 25, so that the connecting block 27 is driven by the two guide springs 39 to slide on the blocking plate 25, the blocking plate 25 is rotatably connected with a connecting frame 28, the connecting frame 28 is in a U-shaped frame structure, straight grooves are formed on two cantilevers of the connecting frame, the two straight grooves are jointly connected with a driving frame 6, the connecting part of the driving frame 6 and the connecting frame 28 can slide or rotate in the straight grooves, and thus, when the vehicle body 1 passes through uneven ground, the blocking plate 25 slides up and down, the connecting block 27 drives the connecting frame 28 to move vertically, however, since the connecting portion of the driving frame 6 and the connecting frame 28 is located in the straight groove, the connecting frame 28 does not drive the driving frame 6 to move along with the vertical movement of the arresting plate 25, but when the guide rod 7 slides on the arresting plate 25, the connecting frame 28 is driven to move through the connecting block 27, so as to drive the driving frame 6 to move along with the connecting frame, as shown in fig. 10, 11, 12, 13 and 14, the driving frame 6 is also U-shaped, and we have the mounting cylinders 3 spaced between two sets of track wheels 37 under the vehicle body 1, one side of the mounting cylinder 3 facing the arresting plate 25 is provided with a through groove, two cantilevers of the driving frame 6 extend into the mounting cylinder 3 from the through groove and are longitudinally matched with the mounting cylinder 3 in a sliding manner, and one end of the two cantilevers of the driving frame extending into the mounting cylinder 3 is rotatably provided with one connecting shaft 5, and two ends of the connecting shaft 5 are rectangular shafts different from each other, the opposite sides of the two connecting shafts 5 are short rectangular shafts, the other sides of the two connecting shafts are long rectangular shafts, the two rectangular shafts are connected through a cylinder, the cylinder is matched with the two cantilever rotating discs of the driving frame 6, so the two connecting shafts 5 can be driven to synchronously move along with the movement of the driving frame 6, the short rectangular shafts on the two connecting shafts 5 are matched with a driving shaft 4 in a sliding way in the same axial direction, the driving shaft 4 is rotationally connected with the two installation cylinders 3, the long rectangular shafts on the connecting shafts 5 are respectively matched with a rotating shaft 2 in a sliding way in the axial direction, namely, rectangular grooves matched with the connecting shafts 5 are respectively arranged at the axes of the two rotating shafts 2 and the driving shaft 4, the two groups of crawler wheels 37, the two rotating shafts 2 and the two installation cylinders 3 are symmetrically arranged along the driving shaft 4, in an initial state, the guide rod 7 is fixed on the blocking rod by a limiting mechanism to enable the guide rod to be incapable of moving, at the moment, the guide spring 39 far away from one side of the curb is still in a compressed state, while the other guide spring 39 is in a stretched state, and in this state, the driving frame 6 is positioned on a symmetrical line of the two mounting cylinders 3, so that the two connecting shafts 5 can be connected with the corresponding driving shafts 4 and the corresponding rotating shafts 2, namely, one rotating shaft 2 of each of the two rectangular shaft parts of the connecting shafts 5 is connected with one end of the driving shaft 4, and thus the two rotating shafts 2 can be driven to rotate by driving the driving shafts 4 to rotate through the two connecting shafts 5, so that the two groups of crawler wheels 37 are driven to rotate, and the whole device advances;

in addition, the device is also provided with a limiting mechanism, so that when the device is not used, the guide rod 7 is limited and does not extend out of the vehicle body 1 too much to cause interference to other people, when the device is used, the limiting mechanism is firstly opened, so that the guide rod 7 is not limited and can freely slide on the stopping plate 25, the end surface of the guide rod 7 is in contact with the side wall of the roadside stone, therefore, if the vehicle body 1 deviates in the moving process of the vehicle body 1, the guide rod 7 is driven to slide on the stopping plate 25 in the corresponding direction, if the vehicle body 1 deviates in the direction close to the roadside stone, because in the figure 1 of the specification drawing of the patent, one end of the guide rod 7 extending out of the vehicle body 1 is arranged on the left side (opposite to the driving direction), the vehicle body 1 deviates in the direction close to the roadside stone, namely deviates in the left side, the roadside stone pushes the guide rod 7 to slide on the stopping plate 25 in the right side of the vehicle body 1, then the guide spring 39 drives the connecting block 27 to move along with the connecting block 27, and the connecting block 27 drives the connecting frame 28 to synchronously move in the same direction, so as to drive the driving frame 6 to slide towards the right side of the vehicle body 1, so that the two connecting shafts 5 move along with the driving frame, and after the driving frame 6 moves for a certain distance, the connecting shaft 5 on the left side of the vehicle body 1 moves towards the other side with the same distance, but the longer rectangular shaft is still connected with the corresponding rotating shaft 2, the shorter rectangular shaft is also connected with the driving shaft 4 and extends into the driving shaft 4 with the same distance, and the connecting shaft 5 on the right side of the vehicle body 1 also moves towards the right side of the vehicle body 1 along with the same distance, and at this time, the longer rectangular shaft slides in the corresponding rotating shaft 2 for a certain distance, and the shorter rectangular shaft gradually disengages from the driving shaft 4, and after the connecting shaft 5 on the right side of the vehicle body 1 disengages from the driving shaft 4, then, along with the rotation of the driving shaft 4, the driving shaft 4 can only drive the connecting shaft 5 connected with it to rotate, that is, the connecting shaft 5 located at the left side of the vehicle body 1 is driven to rotate, but the connecting shaft 5 located at the right side of the vehicle body 1 is not driven to rotate, so that the connecting shaft 5 located at the left side of the vehicle body 1 drives the rotating shaft 2 corresponding to it to rotate, thereby driving the crawler wheel 37 located at the left side of the vehicle body 1 to rotate, and the crawler wheel 37 located at the right side of the vehicle body 1 stops rotating, at this time, under the action of the crawler wheel 37 at the left side, the vehicle body 1 deflects to the right side, and in the process of weighing the body and deflecting, the guide rod 7 gradually moves to the initial position, that is, i.e., slides to the left side of the vehicle body 1, and in the process of moving the guide rod 7, the driving frame 6 is driven to slide to the left side of the vehicle body 1 through the connecting block 27 and the connecting frame 28, thereby driving the connecting shaft 5 to reset, when the connecting shaft 5 on the right side of the vehicle body 1 is connected with the driving shaft 4 again, the crawler wheel 37 on the right side of the vehicle body 1 is driven to rotate again, so that the vehicle body 1 is driven to move forwards again, similarly, if the vehicle body 1 deviates to the right side, because the guiding spring 39 far away from the curb stone is in a compressed state and the other guiding spring 39 is in a stretched state in the initial state, when the vehicle body 1 deviates to the right side, the guiding rod 7 deviates to the left side of the vehicle body 1 under the action of the two guiding springs 39, so that the driving frame 6 is driven to move to the left side of the vehicle body 1 through the connecting block 27 and the connecting frame 28, after the moving distance, the shorter rectangular shaft on the connecting shaft 5 on the left side of the vehicle body 1 is separated from the driving shaft 4, and at this time, the driving shaft 4 can only drive the crawler wheel 37 on the right side of the vehicle body 1 to rotate, so that the vehicle body 1 deviates to the left side thereof, in the process of the deflection of the vehicle body 1, the guide rod 7 is reset against the curbstone until the two connecting shafts 5 are connected with the driving shaft 4, and then the vehicle body 1 can move forwards again, so that the problem of the adjustment of the advancing direction of the vehicle body 1 is solved, in the process, the connecting shaft 5 and the driving shaft 4 are in axial sliding fit, namely, the connecting part of the connecting shaft 5 and the driving shaft 4 is a rectangular shaft, and the axis of the driving shaft 4 is also provided with a rectangular groove corresponding to the rectangular shaft, after the connecting shaft 5 is separated from the driving shaft 4, the rectangular groove cannot be always kept in contrast with the rectangular shaft because the driving shaft 4 rotates, the connecting shaft 5 can be abutted against the end surface of the driving shaft 4 in the resetting process, and because the driving shaft 4 rotates, the rectangular shaft on the connecting shaft 5 can always contrast with the rectangular groove, and then the vehicle body can be connected again under the action of the guide spring 39, in order to enable the two connecting shafts to be connected more conveniently, the notches of the rectangular grooves at the two ends of the driving shaft 4 and the shorter rectangular shafts on the two connecting shafts 5 are provided with chamfers;

referring to fig. 7, the limiting mechanism for limiting the guide rod 7 includes a limiting rod 29 vertically slidably mounted on one side of the blocking plate 25 facing the track wheel 37, the limiting rod 29 is an L-shaped rod, a shifting fork is disposed at a lower end of a vertical portion of the limiting rod, a flange corresponding to the shifting fork is disposed on the guide rod 7, in an initial state, the shifting fork is inserted on the guide rod 7, and one side of the shifting fork away from the curb stone abuts against one side of the flange close to the curb stone, so that the guide spring 39 away from the curb stone is in a compressed state and the guide spring 39 close to one side of the curb stone is in a stretched state in the initial state, and thus under the dual actions of the elasticity of the guide spring 39 and the blocking of the shifting fork, the guide rod 7 is positioned and cannot move easily, the limiting of the guide rod 7 is released, and we only need to shift a horizontal portion of the limiting rod 29 upwards to gradually separate the shifting fork from the flange, the guide rod 7 loses the limit to realize the above-mentioned guide function, in order to avoid that the limiting rod 29 falls down under the action of gravity and the like after being shifted and is clamped on the guide rod 7 again to influence the movement of the guide rod 7, a wedge block 32 is transversely and slidably mounted on the blocking plate 25, a limiting spring 38 is connected between the wedge block 32 and the blocking rod, when the limiting rod 29 is shifted upwards, the horizontal part of the limiting rod 29 is in contact with the wedge surface of the wedge block 32 to push against the wedge block 32 to transversely slide on the blocking plate 25, after the limiting rod 29 is separated from the wedge block 32, the wedge block 32 is reset under the action of the limiting spring 38, the limiting rod 29 is blocked on the wedge block 32 and cannot fall down, thus, the situation that the limiting rod 29 automatically falls down to influence the movement of the guide rod 7 when the device is used is avoided, and the wedge block 32 needs to be shifted after the device is used, so that the stop bar 29 loses the obstruction, the stop bar 29 can be reset.
